What Happened
The Sui blockchain suffered a network stall for the second straight day on Friday, pausing activity and accelerating a sell-off in SUI. The token dropped 20% on the week to $0.89—83% below its all-time high—ranking among the worst top-100 performers. Thursday’s outage lasted over five hours, traced to a gas charging bug in v1.72. The network briefly resumed after a patch, then stalled again Friday. The cause of the latest downtime remains unknown.
The Numbers
SUI plummeted 20% in a week where broader crypto markets showed relative stability. At $0.89, the token has lost 83% from its $5.35 peak. With a market cap of $3.6 billion, Sui remains a major project, but the token’s weekly slide placed it among the five worst-performing assets in the top-100.
Thursday’s outage spanned more than five hours. That follows a six-hour network stall in January 2026, bringing the year’s major downtime count to three significant events. Each hour offline erodes trading volumes and liquidity.
Why It Happened
Thursday’s incident stemmed from a crash bug in the gas charging logic, a core transaction-fee component. The flaw was introduced in the v1.72 upgrade. Friday’s stall may be a lingering effect or a new issue tied to the patch. With three major outages this year alone, Sui’s stability has become a liability. Hailed as a Solana competitor, Sui now faces the same outage scrutiny that once dogged its rival. The network raised $300 million in 2022, yet technical reliability remains unresolved.
Broader Impact
Repeated downtime damages Sui’s reputation among developers and DeFi protocols. DApps cannot function during stalls, and users face potential liquidations or arbitrage losses. The outages feed into a narrative that newer high-performance chains still struggle to match Ethereum’s uptime, potentially slowing institutional adoption. The SUI token’s sharp decline highlights how network reliability directly impacts asset prices. Without quick resolution and transparency, selling pressure may persist.
What to Watch Next
- Incident Review: The Sui team promised a full postmortem in the coming days. Root cause fixes and a patch timeline will be critical for restoring confidence.
- Price Support: SUI at $0.89 is near its lowest since November 2025. A break below $0.85 could accelerate losses, while a swift return to $1.00 would signal stabilization.
- Network Stability: Monitor whether the Friday outage is resolved quickly or extends, as weekend trading often amplifies token moves.
